Overall TCP just always seems to work, and UPD depends on the situation of the network. TCP is better for battery consumption on mobile sip applications as well.
Knowing that TCP uses more overhead just by being TCP, is it really better for mobile phone batteries?
Anecdotal evidence using the built-in Android SIP client (which, while hilariously incapable, does support both UDP and TCP for signalling and is a readily-available common denominator) suggests that the less frequent need to refresh the registration and similar keepalive type mechanisms needed for UDP signalling does indeed make TCP noticeably better for mobile phone battery life.
